A portable lifting curtain

Abstract

Outdoor screens are frequently used, but they cannot be used alone; they must be used with a support frame to unfold and secure them. Existing screen frames are inconvenient to carry, require manual operation, and are not integrated with the screen. They must be connected during use and disassembled afterward, requiring separate storage and transportation, often resulting in loss. We propose a portable lifting screen to solve these problems. The purpose of this invention is to overcome the shortcomings of existing technologies by proposing a portable lifting screen. To achieve the above objective, this invention adopts the following technical solution: A portable lifting screen includes a base frame, a lifting mechanism, and a screen mechanism.

Description

Technical Field

[0001] This invention relates to the field of mobile screen technology, and more particularly to a portable lifting screen. Background Technology

[0002] Outdoor screens are frequently used, but they cannot be used alone; they must be used with a support frame to unfold and secure them before use. Existing screen frames are inconvenient to carry, require manual operation, and are not integrated with the screen. They need to be connected during use and disassembled afterward, requiring separate storage and transportation, which often results in loss. We propose a portable lifting screen to solve these problems. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a portable lifting screen.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A portable lifting screen includes a base frame, a lifting mechanism, and a screen mechanism.

[0005] In one embodiment of the present invention, the base frame mechanism includes a base frame and a bottom that is an integral structure. The upper part is mainly used to connect the lifting mechanism. There are two cross braces at the bottom, and two adjustable legs are installed on the upper part of each cross brace. The cross braces and adjustable legs serve as the overall counterweight of the equipment and are also used to adjust the level of the entire equipment, making the equipment more stable and secure. A battery and a controller are also fixed on the base frame. The battery provides power to the lifting mechanism, and the controller controls the operation of the lifting mechanism. The battery is provided with wires that connect to the power mechanism of the lifting mechanism.

[0006] In one embodiment of the present invention, the lifting mechanism includes a bottom mounting plate. To reduce the weight of the equipment while ensuring sufficient strength, the bottom mounting plate is made of bent aluminum plate. Each side of the bottom mounting plate has an upward-facing lower longitudinal groove. A lower slider is installed inside the lower longitudinal groove. A lower mounting lug is fixed to the other side of the bottom mounting plate. A scissor lift rod is connected to the upper part of the mounting lug. The scissor lift rod is made of lightweight material, and there are multiple sets of scissor lift rods, each with the same structure and dimensions. The other side of the scissor lift rod is connected to the lower slider. Multiple sets of scissor lift rods... Electric push rods are installed between the rods. The power required for the operation of the electric push rods is provided by batteries, and the running direction is controlled by a controller. The uppermost set of scissor lift rods is connected to the upper connecting lugs, and the other side of the uppermost set of scissor lift rods is connected to the upper slider. The upper slider moves along the upper longitudinal slide groove. The upper part of the two upper longitudinal slide grooves is connected to the upper mounting plate. The mounting plate is also made of bent aluminum plate. When the electric push rod extends outward, the scissor lift rods rise, and the lower slider and upper slider move inward. When the electric push rod retracts inward, the scissor lift rods descend, and the lower slider and upper slider move outward.

[0007] In one embodiment of the present invention, the curtain mechanism includes an automatic retractable spring roll bracket, a curtain, and an upper fixing lug. The automatic retractable spring roll bracket is directly fixed to the base frame, and the lower side of the curtain is fixed inside it. The upper side of the curtain is connected to the upper fixing lug. To further facilitate carrying the product, a handle is provided on the upper side of the curtain. When the lifting mechanism rises, the curtain unfolds outward, and when the lifting mechanism falls, the curtain retracts inward.

[0008] The beneficial effects of this invention are: 1. This invention, through the cooperation of the base frame, lifting mechanism and screen mechanism, allows the screen to be unfolded or retracted at any position, making the product convenient to use; 2. This invention is made of lightweight materials, making it convenient to carry when going out.

[0009] In summary, this device solves the problem of using screens in outdoor situations where there are no supports, further expands the usable space, makes things more convenient for users, and has high practical value. Attached Figure Description

The upper part is mainly used to connect the lifting mechanism. There are two cross braces 2 at the bottom. Each cross brace 2 is equipped with two adjustable legs 3. The cross braces 2 and the adjustable legs 3 serve as the overall counterweight of the equipment and also to adjust the level of the entire equipment, making the equipment more stable and secure. A battery 4 and a controller 5 are also fixed on the base frame 1. The battery 4 provides power to the lifting mechanism, and the controller 5 controls the operation of the lifting mechanism. The battery 4 is equipped with wires 6 that are connected to the power mechanism of the lifting mechanism.

[0014] Preferably, the lifting mechanism includes (see appendix) Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 4The bottom mounting plate 7, to minimize the weight of the equipment while ensuring sufficient strength, is made of bent aluminum sheet. Each side of the bottom mounting plate 7 has an upward-facing lower longitudinal groove 8, with a lower slider 9 installed inside the groove 8. A lower mounting lug 10 is fixed to the other side of the bottom mounting plate 7, with a scissor lift rod 11 connected to its upper part. The scissor lift rod 11 is made of lightweight material and consists of multiple sets, each with identical structure and dimensions. The other side of the scissor lift rod 11 connects to the lower slider 9. An electric push rod 12 is installed between the multiple sets of scissor lift rods 11.
